Application filed 3l. H913. Serial No. Mimi jlb :f1/m t :Sona-wn Y le it known that l, EMMA Snr-anwalt). a citizen of the United States, residing :it

New York, in the county of New York und Stato of New York, have invented certain new and noo'fni Improvements in Cuhion ing und Wriora. of which the following is a Spocication, reference boing had therein to tiro accompanying drawing.

M): inwnton rclitrs to cushioning and. holding rapporto for typewriiers and tho like. the general object iioing-io hold the machine Mecnrely upon its ook or support ing bom-fl whilc affording cushioning effoot obvining or lesoening und noise.

Fori' objects are to proriglc the mer chino iis f with :i fleachziblc cushion which maj; no irfod quito indoponenly of holding the machine on the dosi; or Supporting board; to provide for almost instanane onsl.v attaching the machine to iis Support or (letoching it therefrom; and to provide devices whioh are inexpensive and prototically anal-ranged by long use.

1n tho accompanying drawings, Figure. l is a plan View of the devices, the typewriter frame or foot boing omitted. Fig. 2 is a section on the line 2 2, Fig. 1, a portion of the' machine frame being shown. Fig. 3 is ay planview of a portion of the device which is secured. tothe desk or board, Fig. 4 is a sido elevation of that portilon of the device which is carried by the typewrih'n machine itself.

In t les@ views', A reprcsnts the board or desk top to which the typewriter is to he secure, and B a plate having a large ceritrl opening Bland provided with bosses B upon op osito Sides of the lutter and adjacent to t c opening. Upon the bosses, respectively, rest two symmetrically placed arms C having their opposing inne-r margins curved to form approximately a semcirole of a radius materially smaller than that of the opening BG. Through each arm, its boss and the board, in the rear of the center of theopening B", passes an attaching boli;4

D which serves as s'pivot upon which the arm swings firmly in a plane a little above the body of the plaie B. .When the ma chino is removed from the desk or boar, these arms aro normally held gainst sbo D so that their forward encl are wie y separated while te rear portion. of the inl'lolding Supports for Typo' nor margin of anni). 'oroogn weil forward over thc opening ais shown.

The pari of the dcvioo carried lig the ma chine incinfiQ-J a liuelical spring E having al its upper ond; a rigidly connected, centrally open horizontal member E and at its lower end an integral coil cxension flange or pro= joa-.ting lime portion E2. The upper as well *.ne lower of these members i convgilienily formed by properly Winding noifly in n plane, the constituent roti of the helix. lpwardly through the opening in the upper end member of the spring posses ascrew bolt F which haar@ a nut F haring -a lab eral arm F" for engaging the upper edge G of tlio'sorket member il( of the machine. By nrning this .sorrw fromV below by a scrcwririver. or tno like, inserted in ille helix nis ongugci'nent with the machine is mad#` .rgidonfl the machine is thus rovided with a detachable cushion. adapte to rest upon any plane ouraoe, regardlss of other dovices.

"Flic lower. flange, or nearly plane spiral, has its outer turn slightly below the other parte: so that it bears the entiroweight, and his flange initself furnishes a very sensitive and elastic cushion. 'Indeed in some casos, or in some machines, vthe lhelix 'is` screwed into a tubular recess in the machin( frame and serves merely for attachin, the

cushioning being secured by the ngo alone. lnv such crise the omission of the screw or bolt and its not does not destroy the usefulness of thc (lavica. although l prefer to 'employ ille pogiive attachment in all cases. f

To attach the machine to a ,boardprvided' with the devices first described, the

-cushionis placednpon .the front portion of the plato B between the arms C andthe ma chino is pushed rearward, 'the cushion slid in g on the plate. Wien thehelix strikes the rear portions of the arms the latr am swung on their pivots into position. to clasp the helix loosely above the'annnlar external flange formed by its lower member, and as the latter reaches its rearmost position grayvity carries it downwar in the opening 1n the plate until its base rests upon the board vhere it serves as an unchanging cushion which the side of' the opening, in which it lies, prevent from material lateral move- I ment in any direction. The distance of the flange from the arms now directly above it is substantially equa s the thickness of the 'body ofthe thin plate B, and the machine may be fted ifeteej; hmugh this short distance. When so lifted it may be dmw fward ree'y and be thereby detached, cui it cannot move matexey nzmfl other direc tion. In ordinary use there is not-hng t0 lift the machine thus and move it; forwml while lifted, and where the desk s ananged 'for causing the machine t0 disappear, the tendency is to mauve the machine reauwarf and not. fox-ward. It follows the while the nmchuemay be ntentonally eta'ehef er attached almost nstanly, under all possible operating conditions it '1s secure against accflcutel or undesired movement t0 a mate# ra extent in any ,direcvm It isaso ebvous thee the devices carried by the im @hire foe-m a, very useful and compete cushion foatvtaehment to any ordinary mchne. The werd hex sheren use im `conveneuee to designate the body of the spring, but it is intended te designae my analogous, spring whener or not it is of uniform dimeter.
